ACM_CLK_DIV

1 to 4

Set this to the division value to generate the ACM clock, which has a

maximum frequency of 10 MHz. The actual value will be the frequency of

sets the ACM clock at half the PCLK frequency.

Note: It is the user’s responsibility to ensure that the ACM clock has a

maximum operating frequency of 10 MHz.

USE_RTC

0 or 1

Use RTC: Set this to 1 if the RTC is to be used, or to 0 if the RTC is not to be

used. The default value of 0 does not use the RTC.

USE_RDFIFO

0 or 1

Use Read FIFO: Set this to 1 if using an internal data FIFO for storing up to 256

ADC conversion results for later reading by a microprocessor, or to 0 if not

using the FIFO. The default value of 0 does not use a read FIFO.

USE_RDFIFO_AEVAL

0 to 255

Read FIFO Almost Empty Value: Set this 8-bit integer to the fixed almost empty

value of the read FIFO. This value determines when the almost empty flag

output from the read FIFO becomes active; it represents the number of 16-bit

ADC conversion result words that are left to be read before the read FIFO will

be empty.

Note: This is only used if USE_RDFIFO = 1.

USE_RDFIFO_AFVAL

0 to 255

Read FIFO Almost Full Value: Set this 8-bit integer to the fixed almost full value

of the read FIFO. This value determines when the almost full flag output from

the read FIFO becomes active; it represents the number of 16-bit ADC

conversion result words that are left to be written before the read FIFO will be

full.

Note: This is only used if USE_RDFIFO = 1.

FIXED_VAREFSEL

0 or 1

Set this to 1 if the VAREFSEL input pin of the AB macro is to be fixed, or to 0 to

allow register-controlled VAREFSEL setting (saves some logic tiles for a fixed

system). The default value of 0 does not have a fixed VAREFSEL setting.

FIXED_VAREFSEL_VAL

0 or 1

Fixed VAREFSEL Value: Set this to a 1-bit constant value (set in higher-level

wrapper). Set to 1 to select external VAREF as input, 0 to select internal VAREF

as output.

Note: This is only used if FIXED_VAREFSEL = 1.

FIXED_MODE

0 or 1

Set this to 1 if the MODE[3:0] pins of the AB macro are a fixed constant, or to

0 to allow register-controlled MODE[3:0] setting (saves some logic tiles for a

fixed system). The default of 0 does not have a fixed MODE[3:0] setting.

FIXED_MODE_VAL

0 to 2,

4 to 6,

8 to 10,

12 to 14*

Fixed MODE Value: Set this to the integer value of the 4-bit fixed constant

connected to the MODE[3:0] input pins of the AB macro (controls ADC

resolution, etc.).

Note: This is only used if FIXED_MODE = 1.

FIXED_TVC

0 or 1

Set this to 1 if the TVC[7:0] pins of the AB macro are a fixed constant, or to 0

to allow register-controlled TVC[7:0] setting (saves some logic tiles for a fixed

system). The default value of 0 does not have a fixed TVC[7:0] setting.

FIXED_TVC_VAL

0 to 255

Fixed TVC Value: Set this to the integer value of the 8-bit fixed constant

connected to the TVC[7:0] inputs of the AB macro.

Note: This is only used if FIXED_TVC = 1.

FIXED_STC

0 or 1

Set this to 1 if the STC[7:0] pins of the AB macro are a fixed constant, or to 0

to allow register-controlled STC[7:0] setting (saves some logic tiles for a fixed

system). The default value of 0 does not have a fixed STC[7:0] setting.
